My Sisters Top - By zoobleezoo1490
------------------------------
Spring cleaning is always such a drag in my house. Every fucking spring my mom makes us go through all our bullshit and get rid of stuff. Most of the time I end up loosing a ton of shit I would rather just hold on to, but that’s beside the point.

Last week I was going through a bag of laundry my mother was going to give to goodwill to make sure it didn’t have any t-shirts I liked when something happened.. Sorting through all the stuff I came across a blue striped bikini top. I recognized it as my little sister Stephanie’s. She stopped wearing it last year when she turned fourteen. She was just starting to get a little too big for it if you know what I mean. I held it in my hand and paused from going through the rest of the laundry. She used to wear this when her friends would come over in the summer time. She had two girl friends that would come over and they would jump through the sprinkler in the front lawn together in their bathing suits. I would always watch through my bedroom window at them with a huge hard on. The water was always freezing cold and when I saw their nipples poke out through their tops, I couldn’t resist. Several times, when the girls got a little touchy feely as girls do, I ended up jacking off while watching them.

As I stared at thing tan fabric lining the inside of the top, I had a perfect image in my head of my sister in that old blue striped bikini again. She was pulling down the cup of her top and rubbing her nipples.

Then I thought of Stephanie’s giggly friends again… it never did bother me that I was jacking off to a group that contained my sister.. I wonder if that turned me on a little. Now, all I could think about was sucking on her young breasts..

At that moment, I knew that whatever stigma of being wrong was attached to incest, that didn’t matter. Besides what does it matter what I jack off to? I took the bikini top and shoved it into my pocket and ran upstairs as quietly as I could so I could hide my trophy.

I burst into my room with a shock. Stephanie was lying on my bed topless, wearing my old swim trunks from last year. She had one hand down under the elastic waste band at her crotch. When she saw me, she screamed. Thank god our parents weren’t home. As she tried to cover herself in horror, I could see the hand she had in her (my) trunks had a damp index finger. The look of terror she had eased into a puzzled look as she, fingering herself in my old trunks, saw me standing their, holding her old top with a huge hard on. Thank god our parents weren’t home.

Stephanie reached out her left hand, with her right arm covering her pert young breasts.

“Can I have my top please?” She asked meekly in a shaky voice.

Neither one of us wanted to admit what was happening. I held out my hand that was still holding the top reluctantly. I was hoping somehow, that she would let me keep it. I would have let her keep my trunks.. to think of her fingering herself in my trunks..

She took the top and sat it down on the bed. Silence was now louder than a 747 jumbo jet. I said the only thing I could think of.

“Can I have my trunks back?” I asked. Damn I thought. I guess it’s over then.

Stephanie sighed as the tension started to ease. Sure just gimmie a sec. I’ll be right out.

“No” I said without thinking. I was committed. Reason had given way to instinct. One would think at this point, that I wanted to fuck her despite the fact that she was my sister, but now, with the point of no return so far behind me, I wanted to fuck her BECAUSE she was my sister.

“Shorts please.” I said again.

Stephanie bit her lip. I was in.

Our eyes locked. Stephanie brought her hands slowly to the elastic of the swim trunks she had on, revealing her perky breasts for the first time since our initial meeting. Her skin was so pale and supple, the shape of her body so youthful. As she pulled the shorts down and off, my eyes were fixed on the side of her slender nude body. Stephanie’s breasts may have been smaller than most girls, but she was a slender girl.

I reached my hands slowly to unbutton my jeans. Part of me expected her to call for mom to tell on me, but I couldn’t stop. With the button undone, and the fly down, her face was locked on my movements. I watched her eyes light up at I reveled my cock to my sister.

I started to approach the bed. I stepped across the carpet of the bedroom taking of my t-shirt in a swift gesture. She scooted to one side of the twin mattress and made room for me. As I climbed into bed with my little sister, our nude bodies felt like they had been starving for each other for years. There was no more awkwardness. Her little hands grabbed my cock and squeezed really tight. My fingers explored her supple young back and embraced her tightly. …

Stephanie climbed on top of me. My hands immediately found the softness that was her ass. My dick touched the moist opening over her youthful pussy. The warmth and wetness sent a shockwave through my body that made me stop. The moment was broken as she forced herself down onto my dick. The lips of her young womanhood opened up for my rod like brother and sister embracing.

At first she moved her hips forward and backward, letting my cock swivel inside her, then she leaned over and asked in a whisper

“Did Mom leave?”

“She won’t be back for two hours.” I responded.

As soon as I said that the gentle gyrations ceased and she started lifting her little hips up into the air and crashing them down on my cock.

I could not believe the fierceness with which my sister was fucking me. My sister… Now she was starting to moan. With the realization of privacy, she let her feelings flow into our sex without inhibition.

“Oh lover” she cried “I want you to fucking hurt me. Oh god fuck me! Make it hurt!” She screamed. The ecstasy in her voice, the smell of sex in the air, the sweat of my sister’s body all over mine, completely drowned out the sound of jingling keys in the front door.

Mom got divorced several years ago. Recently she has been apt to just kind of disappear from the house for long periods of time. I always figured she was out taking care of things. Perhaps that’s just my being naïve.

I continued to jam my cock into my sister as hard as I could without any idea that our mother was in the house. My young sister had an unbelievable sexual appetite. The more I gave her the more she would take. It reached a point where I was seeing how far I could go. I pulled her hair with one hand and used the other hand to pull her hips towards me while I trusted myself inside her.

I couldn’t take anymore. I had to pull it out before I came. As I tried to yank it out, she resisted. She clung to me like shrink wrap, not letting my cock out of her pussy. She continued fucking my with sharp swivel motions that frankly, kinda hurt.

“Don’t stop now lover” she shouted “Mom put me on the pill, Just let it go inside me!”

I was glad she was on the pill, because by then it was too late. I can tell you this, coming inside of a fourteen year old girl is different than fucking a college slut. You can smell the youth in their sweat. You can lick the innocence right off of them. This is particularly why my favorite part was to suckle gently on Stephanie’s nipples.

Gently I nibbled her breasts as I held my manhood inside my sister. It was over. We had made defiant love to all that we knew to be right. Perhaps that was why it felt so right. Even as the sexual pleasure went away, the smell of sex in the room, and the sweat on our bodies was wonderful. My sister, was now my lover. I only wish my mother had the courage to enter the room instead of listening at the door as we fucked each other. She was a beautiful mother. I would have loved for her to see what Stephanie and I had discovered.
Stephanie and I waited patently for the sounds of our mother who was hiding on the other side of the door listening to skitter off to her room.
Spring cleaning has never quite been the same.
